rate the members when the box cover is` closed.

To this end the invention consists in the features of construction,combination, and

arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure1 is a per spective view of the hinge showing the members separated;Fig. 2 is a perspective view illustrating the method of putting themembers together; and Fig. 3 is a section through a box cover andadjacent wall showing the hinge in position.

' In the drawings A represents the pintle member and B the knucklemember of the hinge. The member B is formed at one end with an opening 2made relatively longer lengthwise of the hinge so as to allow the pintleto be inserted through the opening by holding the same lengthwise ordiagonally of the opening as illustrated in Fig. 2. The pintle beinginserted through the opening 2, the end of the member B formed with theopening is rolled over the pintle to form the knuckle 3. The knucklemember is bent as shown in Fig. 3 to fit over the top edge of the sidewall. of the box and against the inner face of the side wall, theknucklestanding outside the wall. The members of the hinge are securedto the side wall and cover of the box in the usual manner, as by screws4. The opening 2 may be made long enough so as to allow the pintle to beinserted either corner or lengthwise, said opening being narrower thanthe length of the pintle so that when the hinge is in the position shownin Fig. 3 the opening up of the roll 3 will not allow the re-Specification of Letters Patent.

moval of the pintle. It will thus be evident that it will be impossibleto tamper with the hinge when the cover is closed to separate the pintleand knuckle members without separating the pintle member from the coverand turning it to bring the pint-le lengthwise of the opening 2. Thusany tampering with the hinge to separate the members is renderedimpossible.

I claim as my invention:

l. A strap hinge of the class described, comprising a pintle member anda knuckle member, the pintle member being formed at one end with atransversely extending pintle andthe knuckle member being formed at oneend with an opening long enough longitudinally of the knuckle member toreceive the pintle but narrower than the length of the pintle.

2. A strap hinge of the class described, comprising a pintle memberformed at one end with al transversely extending pint-le, the knucklemember beingformed at one end with an opening receiving said pintle,said opening being long enough longitudt nally of the knuckle member toreceive the pintle but narrower than the length of the pintle, the endof the knuckle member being rolled over said pint-le when the parts areinterlocked. y

3. In combination with a box and cover, comprising a strap hinge of theclass described, a flat pintle member to be secured to the underside ofthe box cover and formed at its outer end with a transversely extendingpintle7 a knuckle member bent at right angles to t over the top edge ofthe adjacent wall of the box and against the inner face of the sidewall, the outer end of said knuckle member extending beyond the wall ofthe box and being formed withan opening long enough longitudinally ofthe knuckle member to receive the pintle lengthwise, said opening beingnarrower than the length of the pintle.

In testimony whereof I aiiix my signature in presence of two witnesses.
